Cooperating with the setting wires 12 and 13 respectively are two sets of locking connections for holding a number of the puppet valves out of operation. These locking connections are duplicates of each other and a description of one such set of" connections will he suliicient, for example, the locking connections for holding a number of the bass note puppets (three in the present instance) out of operation comprises a rock-shaft 14 having an arm extending down vertically in position to be engaged by the wire 13. Extending rearwardly from the rock-shaft 14 is an arm 15 which is adjustably connected to the rod 16, carrying a locking plate 17. The locking plate 17 is normally held up by a spring 18. When the locking plate 17 is moved down to engage the tops of a number of puppets will hold said puppets down so that they will. be rendered inoperative, permitting the use of a narrow sheet upon the tracker board T. One particular advantage of the use of a narrow music sheet attachment for musical instruments constructed according to this invention resides in the fact that the range of the cut-oil devices may be increased to any de sired extent. For example, while I have illustrated. cut-oll connections adapted to make a change of six notes only in the capacity of the instrument, it is understood that this can be readily increased by substitution of larger locking plates 17, which can be readily put in and taken out according to the character oi the change in Width of the music sheet to which it is desired to adaptit to any particular instrument.

I am aware that changes may be made in practicing my invention. by those who are skilled in the art in applying my invention to dill'erent forms of instruments. l (lo'not wish, therefore, to be limited to the particu-- lar construction I. have herein shown and described, but

In a music playing device, t,he c0mbination of primary pncumatics, puppets controlled thereby, a locking plate, means for normally holding the locking plate out of operative position, a rock-shaft connected to move the locking plate and a setting handle for tipping the rock-shaft to operate the plate to hold the puppets from 0perating, which correspond to notes beyond range of the music sheet which it is desired to use.

5. In a music playing device, the comhination of primary pneumatics, puppets controlled thereby, a locking plate for certain of the puppets, a spring normally holding the locking plate out of operative position, a rock-shaft for setting the locking plate, a slide wire and a setting handle for operating the slide wire.

6. in a music playing device, the combination of primary pneumatics, puppets controlled thereby, two locking plates for preventing the puppets from operating which correspond to the bass and treble notes rc' spectively which are beyond the range of the music sheet which it is desired to use, a setting handle and connections for operating both of the locking plates from the setting .handlc.
